Abstract

Mechanically shakeable mixing vessel with a pre-metered amount of gypsum powder comprising additives, an injection port for water and an attachable ejection tube for the direct application of the gypsum paste into the mouth of the patient, characterised in that the mixing vessel contains a defined amount of gypsum powder with additives to which a defined amount of water is added, the injection port being sited such that the interior of the mixing vessel is rendered accessible by retracting the plunger for introducing water and sealed again by advancing the plunger (see Fig. 3), so that no gypsum water or gypsum paste can flow out during shaking, the application tube being designed such that on introduction into the mouth the rear teeth areas, in particular, can be reached without any obstruction by the cheek. <IMAGE>

Description

BESCHREIBUNG DESCRIPTION

Titel Mischbehälter mit vordosiertem Gipspulver zur Herstellung eines Bißnahmeregistrates ("Gipsschlüssel") Anwendungsgebiet Der Mischbehälter ermöglicht dem Zahnarzt am Patienten die Herstellung eines Bißnahmeregistrates (Gipsschlüssel = massives Gipsteil mit Impressionen der Oberkiefer-und Unterkieferzähne) aus Dental-Modell-Hartgips.Title Mixing container with pre-dosed plaster powder for the production of a Bite registration registers ("plaster key") Field of application The mixing container enables the dentist the production of a bite registration on the patient (plaster key = solid plaster part with impressions of the upper and lower teeth) made of dental model hard plaster.

Zweck Der Mischbehälter wird bei der Bißnahme (Orientierung der Oberkiefer-und Unterkieferzähne zueinander) im Rahmen von pro te tischen oder anderen zahnärztlichen Behandlungen angewendet. Mit ihm ist die Herstellung eines Gipsschlüssels am Patienten möglich, der dem Zahnarzt oder dem Zahntechniker in den darauf folgenden ArbeitsgängenE Çs Ar eit sezzeensudnetreriOag8lldeievoth BbUerrKi und Unterkiefer in den Gipsschlüssel ist es möglich, die Modelle in der durch die Bißnahme vom Zahnarzt angegebenen Beziehung zueinander in einem Artikulator einzuartikulieren Stand der Technik Hilfsmittel für die Bißnahme sind bekannt. Im wesentlichen werden zur Herstellung eines Bißnahmeregistrates verwendet: (1) Thermoplastische Materialien (Wachse, Kompositionsmassen) (2) selbst härtende Kunststoffmassen, Silikone, (3) auf Trägermedien aufgebrachte selbsthärtende Pasten, (4) Abdruckgips Alle vier Materialgruppen haben gravierende Nachteile. Bißregistrate aus Thermoplastischen Materialien unterliegen temperaturabhängigen Verformungen. Themperaturschwankungen beim Transport der Registrate von der Zahnarztpraxis in das zahntechnische Labor können das Registrat verändern und so die Bißnahme verfälschen.Purpose The mixing container is used when taking a bite (orientation of the upper jaw and Lower jaw teeth to each other) in the context of prosthetic or other dental Treatments applied. With it is the production of a plaster key on the patient possible, which the dentist or the dental technician in the subsequent work steps E. Çs work sezzeensudnetreriOag8lldeievoth BbUerrKi and lower jaw in the plaster key it is possible to use the models in the relationship indicated by the dentist taking the bite articulating aids to each other in an articulator for taking bites are known. Essentially, they are used to create a bite registration used: (1) thermoplastic materials (waxes, composites) (2) itself hardening plastic compounds, silicones, (3) self-hardening ones applied to carrier media Pastes, (4) plaster of paris All four groups of materials have serious disadvantages. Bite registrations made of thermoplastic materials are subject to temperature-dependent deformations. Temperature fluctuations when transporting the registrations from the dental practice in the dental laboratory can change the registration and thus falsify the bite registration.

Selbsthärtende Kunststoffmassen haben eine Enthärtungskontraktion oder sind nach dem Erhärten elastisch verformbar (Silikone), was zu Fehlern bei der Einartikulation der Modelle durch den Zahntechniker rühren kann. Self-hardening plastic compounds have a softening contraction or are elastically deformable after hardening (silicone), which leads to errors the articulation of the models by the dental technician.

Die zur Bißnahme verwendeten Pasten sind nach dem Abbindevorgang nicht lagerstabil. Sie unterliegen Dimensionsveränderungen durch Austrocknung. The pastes used for bite registration are after the setting process not stable in storage. They are subject to dimensional changes due to drying out.

Registrate aus Abdruckgips haben keine ausreichende Härte. sie zerbrechen leicht und unterliegen einem Abrieb, der die Einartikulation verfälschen kann. Registrations made of plaster of paris do not have sufficient hardness. they break light and are subject to abrasion that can distort the articulation.

Aufgabe Konstruktion einer Apparatur zur Herstellung eines Bißnahmeregistrates im Munde des Patienten mit guten Verarbeitungs- und Lagereigenschaften.Task Construction of an apparatus for the production of a bite registration in the mouth of the patient with good processing and storage properties.

Lösung Es wurde ein Mischbehälter konstruiert, der es ermöglicht, Dental-Modell-Hartgips bei der Bißnahme im Munde des Patienten zu verwenden. Der Mischbehälter enthält eine vordosierte Menge Gipspulver. Durch eine Einspritz-Öffnung wird eine vorbestimmte Menge Trimmer-Wasser (Aufschwemmung von zermalenem, abgebundenen Gips einer vorgegebenen Konzentration) hinzu gespritzt, der Mischbehälter wird maschinell gerüttelt und dient sofort im Anschluß daran durch ein auf einen Konus aufsteckbares Ausspritzrohr zum Einbringen des Gipspulver-Trimmerwasser-Gemisches direkt zwischen die Zähne in den Mund des Patienten.Solution A mixing container was constructed which enables To use dental model hard plaster when taking a bite in the patient's mouth. Of the Mixing container contains a pre-dosed amount of plaster powder. Through an injection port a predetermined amount of trimmer water (suspension of crushed, bound Plaster of paris of a given concentration) is injected, the mixing container is mechanized shaken and is used immediately afterwards by a pluggable onto a cone Spray tube for introducing the gypsum powder / trimmer water mixture directly between the teeth in the patient's mouth.

Vorteile (1) Durch die Verfügbarkeit des vorgefertigten Mischbehälters mit vordosierter Gipspulvermenge und Trimmer-Wasser entfallen weitgehend Maßnahmen zur Vorbereitung der Hilfsmaterialien zur Bißnahme (Wasserbäder, Wachsplatten, Anmischbestecke usw.).Advantages (1) Due to the availability of the prefabricated mixing container With a pre-dosed amount of gypsum powder and trimmer water, measures are largely unnecessary to prepare the auxiliary materials for bite registration (water baths, wax plates, mixing utensils etc.).

(2) Die Verwendung des Mischbehälters durch Aufstecken des Ausspritzrohres zum Einbringen des Gipses in den Mund vereinfacht den Vorgang der Mißnahme am Patienten. (2) The use of the mixing container by attaching the spray tube for introducing the plaster of paris into the mouth simplifies the procedure of taking measurements on the patient.

Das Einbringen der Hilfsmittel von Hand mit Pinzette, Trägerfolie usw. Inserting the aids by hand with tweezers, carrier film etc.

entfällt. not applicable.

(3) Die guten Materialeigenschaften des Dental-Modell-Hartgipses, nämlich Thermostabilität, geringe Abbindeexpantionen, unbegrenzte Lagerfähigkeit und geringer Abrieb ermöglichen: a) einen zeitunabhängigen Transport des Bißnahmeregistrates von der zahnärztlichen Praxis zum zahntechnischen Labor ohne Gefahr der thermischen oder mechanischen Verformung des Registrates, b) eine unkomplizierte Weiterverarbeitung des Registrates durch den Zahntechniker ohne Gefahr der Zerstörung oder Veränderung des Registrates, c) eine exakte Übertragung der Bißnahme auf die Modelle im Artikulator, d) eine Lagerung der Registrate für spätere Feststellung einer etwaigen Bißlageveränderung am Patienten. (3) The good material properties of the dental model hard plaster, namely thermal stability, low setting expansions, unlimited shelf life and low abrasion enable: a) a time-independent transport of the bite registration from the dental practice to the dental laboratory without the risk of thermal or mechanical deformation of the registration, b) uncomplicated further processing of the registration by the dental technician without the risk of destruction or change of the registration, c) an exact transfer of the bite registration to the models in the articulator, d) a storage of the registrations for later determination of a possible change in the bite position on the patient.
